The vulnerability exists due to the system's authorization functionality does not prevent gaining access to user's data or record by modifying the key value identifying the data. A remote authenticated attacker can send a specially crafted request to the "graph_json.php" file with a modified "local_graph_id" parameter and view the graph data.

2) SQL injection (CVE-ID: CVE-2019-17357)

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in graphs.php. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.


3) Deserialization of Untrusted Data (CVE-ID: CVE-2019-17358)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in lib/functions.php. A remote attacker can pass specially crafted data to the application and execute arbitrary PHP code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Stored cross-site scripting (CVE-ID: CVE-2020-7106)

The vulnerability exists due to insufficient sanitization of user-supplied data in the "description" parameter. A remote attacker can permanently inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

This vulnerability affects the following files:

  • data_sources.php
  • color_templates_item.php
  • graphs.php
  • graph_items.php
  • lib/api_automation.php
  • user_admin.php
  • user_group_admin.php

5) Input validation error (CVE-ID: CVE-2020-7237)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insufficient validation of user-supplied input in the Performance Boost Debug Log field of "poller_automation.php". A remote authenticated attacker can execute arbitrary code via shell metacharacters.
